Be it known that I, J EAN PIERRE FRANors CARTIER, a citizen of the French Republic, residing at Doussard, France, have invented a new and useful Oil-Press, of which the following is a specication.

Figure l shows a vertical section of one form of this apparatus; Fig. 2, a similar view of another form; Fig. 3, a plan of t-he base-plate; Fig. 4, a section ou line in either of Figs. 1 and 2; Fig. 5, a plan of a perforated plate, E, hereinafter referred to. Fig. 6 represents a plan or top View of the piston.

This apparatus consists ofa cylinder or vessel, B, of preferably cylindrical shape, resting on a base-plate, A, having an aperture in the center and a gutter or channel and spout. (See Fig. 3.) Through the central aperturein the plate A passes the rod of a piston or hydraulic ram. (Notshown.) Thepiston-headCmoves in the aforesaid cylinder B. At its lower part it has a channel corresponding with that of the base-plate, and is suitably perforated. The piston carries a plate, E, also perforated and covered with a llter-cloth, F, say, of hair or Wool.

The top of the vessel B is covered with a lid, D, also provided With a perforated plate, E, and a filter-cloth, F. The lid can be raised or lowered by a screw, V. On the top of the vessel there is a channel for gathering the liquid forced out at the top. It may be connected with the spout. (See Fig. 1.)

invention and in what manner the same may be carried into practical effect, I wish it to be understood that what I claim, and desire to protect by United States Letters Patent, is-

In oilpresses, thc combination of base A,

having central aperture and formed with cirg cular channel and spout, vessel B, having in its top a channel communicating with said spout, perforated piston carrying t-he perforated plate eovered with filtering material, and the cover D, also provided with a perforated plate and filtering media, substantially as described.

In witness whereof I have hereto setmy hand.
